FASTENlNG-DRIVING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 251,756, dated January3, 1882. `Application filed November 161 1881. (No model.)

To all 'whom tt may concern:

Be it known that I, EEAs'rUs WoonWARD, of Somerville, in the county ofMiddlesex and State of Massachusetts, a citizen of the United States,have invented a certain new and useful Improvement in Fastening-DrivingMachines, of which the folloang is a l'ull, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specilication in explaining its naIure',.in which- Figurel'is a side elevation of my machine. Fig. 2 is an elevation of aportionthereofupon the opposite side from that shown in Fig. l. Fig. 3 is aplan of a part of the treadle mechanism. A

This invention is an improvement upon those described in Letters PatentNo. 246,437, granted me August 80,1881, i'or improvement intacking-machines, and Patent No. 248,544 for lasting and fasteningmachine, dated October 18, 1881. In the last-named patent I havedescribed afastening-driving machine so organized that the act ot'presenting the work to the fastening-driving machine in proper positionto receive the fastening automatically starts and stops the machine, andthat the parts automatically resume .their original position. In lieu,however, of starting and stopping the fastening-driving machine by theWork, I herein describe a modified form loi" construction which Iconsider in its broad features to be covered in said last-namedapplication, but which, being somewhat diierent in construction, isentitled to specific protection. It consists ot' the use of afoot-treadle and intermediate mechanism for operating the start and stopmechanism of the fastening-4 driving machine in addition to thefoot-treadle l'or operating the jack in the manner described in saidapplication. In all other respectsthe mechanism is like that describedin said 1patent-s, with the exception that the braking or frictiondevice described in another pendingapplication tiled September 27, 1881,is also used.

A is the treadle for operating the jack A.

B is the fastening-driving machine. B is its nozzle. C isayieldingguide. D is thetreadle for operating the start and stop motions. D is anarm which in part is the equivalent of the lever d ot said Patent246,437. It has at its end the latch d, (the equivalent ofthe latch d ofsaid patent,) which engages with the pin d on the lever d2, which leveris the same as the lever d2 of the patent. A connecting-rod, d3,connects the end of the treadle D with the latch-arm. As the treadle ispivoted at d4 it follows that upon the downward movement ot' its frontend its rearendisliit'ted, thereby lifting the latch-arm, dropping thelatch, and permitting the movable member of the clutch to engage withthe fixed member, as described in said patent. Then by gravity the latchfalls upon the pin and is operated by the cam to unship the clutch, asindicated in the patent.

In operating the machine the operator controls the movement ot' the jackby one treadle and the actuation of the start and stop mo tions by theother treadle.

Having thus fully described my invention,

ERASTUS WOODWARD.
